It means water treated or supplied gaseous oxygen
Answer:
When you release the opening of the balloon, gas quickly escapes to equalize the pressure inside with the air pressure outside of the balloon. The escaping air exerts a force on the balloon itself. ... That opposing force—called thrust, in this case—propels the rocket forward.
distance(d) = speed(s) × time (t)
= 22.3 × 8.5
= 189.55m
V = dx/dt = (-33/15)t^2 + 3.1
When v = 0 we need to find t => (33/15)t^2 = 3.1 => t = 1.19
a = dv/dt = (-66/15)t At t = 1.19, a = - 5.23
